Champions Online devs have published an article about two of the Mystic powers: Sorcery and Supernatural. Find out a bit about them below:
Currently, Sorcery is one big power set with many different aspects to it. You've got "Circles of Power", which create areas that, if you stay in them, give you a very strong buff. If you leave that circle, you lose the benefit. "Auras" grant a buff to you and your teammates. "Circles of Summoning" summons a critter that can leave the circle to attack an enemy as long as you stay in the circle. Circles of Summoning and Circles of Power are mutually exclusive, meaning you can only have one or the other up at any time. You can also have one Aura up at any time in addition.
...
Supernatural is a set intended to let you create a character that is supernaturally inspired: angelic, demonic, etc. Their powers are like, "Condemn your enemy with bolts of holy doom," "Infect your enemy with clouds of pestilent flies," "Bite your enemy and drain their living essence to yourself," and "Summon animals from the wilderness to serve your will."
